    Is that the Cadillac R&amp;D Northstar V8? I think the numbers were the other way around. 750 HP and 450 lb ft. It's a short stroke hi revver so it makes tons-o-HP. There's an article in Popular Mechanix about it this month. Expect it to be highly detuned though before it goes into production. [​IMG]

    Think they can modify the tooling for the old V4-6-8 badges?

    I'll stick with my 6 on all the time, thanks.

    It's a Caddy V12 and the numbers are the other way, 750 HP and around 450-500 lb-ft. The article is in one of the big 3 off road mags, I think it's Off-Road. The article says it makes 90% of it's torque at 1500 RPMs. It's displacement on demand shuts down one side of the engine so it runs as a balanced V6 on the highway. I'm still not thrilled with that crap but if they get it to work, I guess it would be nice for milage on the highway. It's also got variable length intake runners so they can change the flow for higher torque or HP, whatever is needed across the RPM range. They're running direct gas injection too so it should get increadible milage and emissions levels. Supposedly it's coming out next year in a Caddy and trucks in the next year or two. It's the same length as the 8.1L and height and width are the same as the 6.0L so it should drop in the truck pretty easily. Wouldn't it be nice if they switched over to the straight axle for the HD trucks AND dropped this engine in!!! That'd make one hell of a tow vehicle.

    You don't necessarily need a straight axle for highway towing (I actually prefer the IFS for towing on highway unless you have the incorrect amount of tongue weight), but I do get your point. This engine combined with a straight axle would make one heck of a heavy duty work truck. And could trailer a heck of a load in the rough stuff (without having to worry about the weaknesses of IFS, although they are getting better).
    As with anything time will tell.

    Yeah I read about that, and it's about the size of a V-8 too. Cool.

    A computer once beat me at chess, but it was no match for me at kick boxing.
